The simple way to calculate cost is $1 per watt per year. This is based on a cost of about 11 cents per kilowatt hour. Your cost may vary.
So, 60 watts times 1/2 year (12 hours /day) divided by 12 ( 1 month) equals $2.50 per month.

How much does it cost to burn 7.5 watt night light bulb?
The bulb uses 7.5 watt-hours each hour, or 90 watt-hours if left on for 12 hours. 1 unit of electricity would be used in 11 days at 12 hours per day.
If I Leave light on for 2 days straight?
You cannot leave it becuase the bulb will burn out and then probably do some damage to your house. You can if you close the lights after a few hours then turn it on again. Good luck!
Why would a light bulb burn out after two days of use?
If a light bulb is handled roughly before it was installed, the filament holder could have been weakened. Another reason that bulbs burn out before their time is that they are being submitted to a higher voltage than the bulb rated for.
How much does it cost to use a 100 watt 120 volt light bulb?
At 10 cents per kWh (Kilowatt hour), one 100 watt incandescent light bulb ran for 24 hours straight will cost 24 cents a day. $7.30 a month, $87.60 a year. kWh = (Watts Used * Hours per Day * Days per Month) / 1000 Cost per Month = kWh * Cost per kWh
How long does a normal light bulb last?
A flourescent light bulb lasts between 6000 to 18000 hours.
If a 100 w light bulb is lit for 8 hours each day for W days in a month many kilowatt-hours will the bulb consume?
Convert the 100 watts to kilowatts. Calculate the total time in hours, and multiply by the number of kilowatts that the light bulb uses.
Why life of a bulb ends after certain time span?
By bulb, it is assumed a light bulb is intended rather than a flower bulb or any other kind of bulb. Light bulbs burn out because they are engineered to do so. There would be less profit to the bulb manufacturer if he made bulbs to last longer, which he could if he wanted to. In the early days of bulb manufacture, a bulb was made which still continues to burn over 110 years later. See the link below for more information on the 110 year bulb.
What is the Average cost of running a 60 watt bulb for a year?
The average cost of running a 60 watt bulb for a year, with an average electricity rate of $0.12 per kilowatt-hour, would be around $52.56. This calculation is based on leaving the bulb on for 8 hours a day for 365 days.
A light bulb consumes 19800 watt-hours in 5 days and 12 hours How many watt-hours does it consume per day?
5 days 12 hours = 5.5 days19,800 / 5.5 = 3,600 watt-hours per day = 150 watts
How do you compute electrical consumption of a device?
To compute the electrical consumption of a device, you need to know the power rating of the device in watts and the duration of use in hours. The formula is Power (in watts) x Time (in hours) = Energy consumption (in watt-hours or kilowatt-hours). You can use this information to estimate the cost of running the device by multiplying the energy consumption by your electricity rate.
